Background
Pilocytic astrocytomas are the most common primary brain tumors in children. Most of the lesions occur in or near the midline. They are rare in extra-axial locations.
Case presentation
We report a 23-year-old lady who was found to have progressive right-sided sensorineural hearing loss and features of raised intracranial pressure due to a pilocytic astrocytoma of the right cerebellopontine angle. After an extensive Medline search, we could find only three cases of primary extra-axial pilocytic astrocytoma of the cerebellopontine angle (CPA) reported till now.
Conclusion
Even a rare occurrence, primary pilocytic astrocytoma, and in general gliomas, should be kept in mind in the differential diagnosis of CPA lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
